A short story by Aesop (author of Aesop's Fables)

The Boasting Traveler

A Man who had traveled in foreign lands boasted very much, on returning to his own country, of the many wonderful and heroic things he had done in the different places he had visited. Among other things, he said that when he was at Rhodes he had leaped to such a distance that no man of his day could leap anywhere near him--and as to that there were in Rhodes many persons who saw him do it, and whom he could call as witnesses. One of the bystanders, interrupting him, said: "Now, my good man, if this be all true, there is no need of witnesses. Suppose this to be Rhodes and now for your leap."
